I get a harsh shift between 1st and 2nd, all other shifts are perfect, I only have 75,000 on my 1992 Camaro. Transmission has never been beat or abused, everything else with the transmission is smooth as glass, the harsh shift happens at about 2800 RPM, I want to know what I can do about this and if this is normal or not. Its just anoying now then and then when it's really cold.

 

Take it to several tranny shops for their opinion.
Simple, and free.

No Thanks, I had a chance to work on it today and read my factory Manual, the TV cable from the butter-fly to the tranny is bindding so is messing up that shift, I almost got it fixed but, I just want to know if anybody else has this problem before.

 

Has the fluid been changed every year? What color is it? Luckily you have a '92 transmission, the earlier guys weren't as well built. (I'm on my 3rd rebuild of my '86 trans...)

Yes I had the transmission done with a WYNNS transmission flush 2000 miles ago.

 

How long ago before that was the trans fluid done? Do you remember the color/smell/feel of the old fluid? If it was dark brown/smelled burnt/felt gritty, your trans could be in trouble. 700r4's should have their fluids regularly; compared to other transmissions, the 700r4 produces more heat, which kills the fluid faster than other trannies do. It's not so much mileage with our trans fluid, but heat...

You can visually check the TV cable for a bind. Find the TV cable... look at the green plastic **** that holds it to the throttle body's linkage. At the "front" of the green link is the end of the cable. The end of the cable should be against the green link- if the end isn't resting against the link, the cable's binding.

Have you re-set the TV cable? Our old friend Scoob wrote up a great tech article about it under the thirdgen.org tech section- here's the link: https://www.thirdgen.org/newdesign/tech/detent.shtml Personally, I need to use a screwdriver to push the metal tang in. There's a small hole in the center of the tang that my screwdriver digs into.

Altho.. I'd think if your TV cable wasn't adjusted properly, your shifts wouldn't be as strong, and they'd come really early.

I don't know before this point, it might have been done, because the guy before me took good care of it, but like I say, I brought my 1992 Camaro with 48000 in '97, I'm only up to 71000, so your saying the TV cable is the one with the green end, I thought it was the lower one thats black.

 

Hey thanks TomP, I did the TV Cable adjustment just like the page you said and that did the trick,,, smooth as glass. Thanks for the page link

 

Glad to hear it worked, Ryan! Keep that yearly trans fluid & filter change in mind! You wouldn't have to go thru the full flush again... you could just drop the pan, drain out the 5 or 6 quarts of old fluid, and put 5 (or 6 depending on what comes out) back in. How much did they charge for that full flush?

I've been told the flush can be done without any special tools... you unhook the fluid return line at the transmission, and aim it towards a bucket. Then you start the car.. the tranny's fluid pump will push fluid out of the trans- and into the bucket. As this happens, you pour new trans fluid into the trans dipstick.... when you see new fluid pouring into the bucket, you're done.

Except for the joys of reattaching that tube!
What size pan did you use?
Was it the top or the bottom tube?

Well I won't recommend doing what your saying because that would leave the transmission running dry if you did it your self by letting it pump itself dry, and dropping the pan does not get the stuff out of the converter and thats the biggy. What they do is, first drop the pan and put in a new filter MOST IMPORTANT, then they unhook the cooler lines from the front cooler and they hook them up to a DC pump that pumps CLEAN fluid back into the transmission,,,, they do this until it's clean, and I mean clean, where talking 10min flush,,, last they hook it all back up and clean up THE MESS,,, lol,,, all for $100 bucks which includes TAX. IT"S WORTH IT, I know because you can feel the difference. And you get to watch if you go to Jiffy Lube or someplace.

 

One thing I forgot to add was the car is running when they do the flush and they go through all the gears to clean the valve body, and they use about 20 quarts when they do this flush.

 

Oh, no, you misunderstood me. At no point do you run the tranny dry! As the engine runs, it spins the torque convertor, which spins the fluid pump. The fluid pump sucks the old fluid out of the trans (and into the bucket), you pour new trans fluid in. It's the same as the flush you got, except "manual labor" instead of "hook up the machine/automatic labor". Since the fluid pump runs off the torque convertor, so you get at the fluid inside that, too.

20 quarts, wow! That's a lot of fluid.. what's the "full rebuild" fluid requirement again? 12 quarts? For $100 though that beats the "manual labor" deal... especially since $30 of that is fluid.

And don't forget,,,, they take that pan off and on which is $30 labor added to the bill,,, plus the filter,,,, and the best part is they CLEAN UP THE MESS,,,, I hate that fluid mess,,,, I helped my dad change and automatic on a Ford Van one time and the converter fell out when we where taking it down off the fly wheel,,, what a mess,,, but we did it, worked great
